I don't want travel points, I've had Discover for 25 yrs at least. It works well for me, you can take your Cash Back money earned and use it to pay towards the next bill. But I use it to buy gift cards because you get more for your money, i.e.: a $25 gift card, only costs you $20. I use it often for Lands End, I get a gift card, I navigate to LE by going through the Discover website, that alone gets me an extra 5-10% cash back on my LE purchase. And then I buy clothes on clearance and I wait for a 30% off clearance sale. So 25% more to spend using the gift card, 5-10% earned in more cash back and clothes are dirt cheap. Wherever I shop, I just check to see if it's a store that will give me 5-10% back in cash back just for navigating to it through Discover, you can still use all the store benefits, i.e.: free ship if you spend $25, coupon codes and the stores own codes, etc.
Discover also chooses categories throughout the year that will earn 5% cash back, like groceries and dept stores, etc. I think this card has served me well.
